7. 3 kw INDUCTION HOB

[davesparks]

Completely and fully agree that gas is far superior for a hob, but a common reason for changing to electric is to avoid costly annual gas checks in rented property.

This may be a regional difference but around here if a property has a gas supply then it is pretty likely to have gas heating too which negates that potential saving.

I would certainly be very upset if my landlord replaced the gas hob with electric, it was the main selling point for the flat as far as I was concerned when I viewed it.

Gas heating and water changed to electric or oil as well, although my experience is mainly with LPG rather than natural gas.

I'm surprised that makes financial sense, a landlords gas inspection doesn't cost that much.

I wonder if it has anything to do with it being LPG and that being a different situation.

Doesn't make sense (for the landlord) to just go in and do it, but when the property is being renovated, it does.
I have LPG hobs in my own house, but all the holiday cottages are electric cooking.

From a landlords point of view, electric oven and hob have benefits over gas both for, safety, and maintenance costs.

Gas for heating.

Old thread, but for anyone with the same question who finds this, I'll add a picture from a Whirlpool cooktop manual.
It has two power inputs and appears to be quite flexible with voltage and phase.

So depending on your particular hardware, the answer may be technically yes, but would go against local code in UK and Australia.

Hello,
i got slightly lost... what 1pole CB should be used with 7.3kw hob? ie how many ampers and what curve?
and also are we talking about 4 or 6mm cable?


edit> seems 32A, no clue regarding its curve and 6mm2 should be ok?


Appreciate.

Sorry.

With respect, you are considering a brand new circuit. That is notifiable work and not a DIY project.
You need a registered electrician to do this work for you, to test, certify the installation and notify the local authority that the work complies with building regulations.

@Taylortwocities not going to do it by myself.

Just want to know and check hows the cable will look like... and want to buy online material... work will be done by certified guy.

Simple, just ask your electrician what they want you to order.

The bottom line is that a number of factors need to be taken into account in determining cable size and these would require knowledge no one here is in possession of. A quick visit from your electrician would provide the answer.

he should come on next week... but in the general i dont believe to these ppl here in the country where i am located atm.
so 2nd opinion should be nice.

and here 7.6kW Induction Hob - need to select cable and fuse size - https://www.electriciansforums.net/threads/7-6kw-induction-hob-need-to-select-cable-and-fuse-size.68239/page-2#gsc.tab=0 they clearly stated
32A, 6mm...

That’s your second opinion then.

When I was “on the tools” I hated customers who bought their own materials. Often it was just plain wrong, or some cheapo tat that wouldn’t last a week. Or it hadn’t arrived. All of these added to time on thd job, and cost the customer more ££.
On more than one occasion I’ve just walked out to another job.
Look, It’s a new circuit. You’ll need a registered electrician, he/she has trained for years, is competent and is assessed annually. Trust him/her, you won’t save any money.

Bc I am currently in Czechia
I do not trust these people at all.

I am not in west eu or US... So it's pain here. So many diletans and I can imagine how they are assessed :/

Surely it's a three-phase supply there rather than a large single phase supply? You really need someone familiar with Czech wiring regulations and practices.

@Risteard
i have electrian visit next week, i believe there is also 3-phase supply, do i have to ask him to setup it in 3-phase way? is that better then single phase supply with one big CB?

thanks

He said i have 1phase 25A CB, and he said that my induction 7.3kw should work with it... that these are modern and know how to regulate power....

but he suggested that i should go for 2x 25A CB setup.

Confused.

It would probably work fine on the single phase due to diversity if nothing else.
